Force does not relate power directly like you state. But I did find an article reducing certain properties to a generalized force statement as follows:
The maximum force per unit area (which is pressure) which an iron core electromagnet can exert is approximately 145 lbf/in². See the physics section here: https://en.m.wikipedia.org/wiki/Electromagnet
You had given a brief discussion on electromagnet force in post #1232 and included this from one of the references:

Again you can see that the expression does not contain power or terms which could lead directly to a power or energy calculation. To do that, certain constraints must be defined.
